I don’t know what your learning style is, but are a couple thoughts off the cuff.
Watch the video with Cubase running and switch back and forth between the two. Try to take in smaller bursts of info at a time.
Just focus on one item for a session, like one of the editors, and do a specific task.
And definitely, ask questions. There are a lot of helpful people here, even the grumpy ones want to help out someone who’s made the effort. We have all been there, for sure. (Plus the average age here is, golly, well, Middle.)
